摘要： An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.

摘要： Stabilized indicator compositions, and systems and methods using the same are described. In embodiments the stabilized indicator compositions include a solvent, an indicator, a stabilizer for the indicator, and optionally a buffer. In embodiments the indicator is or includes N, N-diethyl-p-phenylene diamine (DPD). Systems and methods utilizing the stabilized indicator composition to determine an amount of at least one constituent in a test sample (e.g., water) are also described. In embodiments, the systems and methods remove the stabilizer from the stabilized indicator composition to produce a fluid flow containing un stabilized indicator, which is then combined with a fluid from a sample source to form a test sample for analysis.

摘要： A universal respiratory detector for detecting a respiratory gas. The universal respiratory detector may include a plurality of layers with a visual indicator to quickly and reversibly change color to detect a respiratory gas parameter such as carbon dioxide.

摘要： This present invention relates generally to devices, systems, and methods for performing optical and electrochemical assays and, more particularly, to devices and systems having universal channel circuitry configured to perform optical and electrochemical assays, and methods of performing the optical and electrochemical assays using the universal channel circuitry. The universal channel circuitry is circuitry that has electronic switching capabilities such that any contact pin, and thus any sensor contact pad in a testing device, can be connected to one or more channels capable of taking on one or more measurement modes or configurations (e.g., an amperometric measurement mode or a current drive mode).
